Don't see where you can count widget on a sheet and then add to count on another sheet. Also don't see where you can see specifically what you counted on the sheet you're currently on.
I did see how to do this, by clicking in right pane while on new page. Would be nice to be able to see only qty's per sheet selected maybe on another pane?
Just hover over the takeoff item and click the + icon to continue a new section. No more double click on takeoff item to draw more. In the future double click on the takeoff item will open properties.
